About this calculator

Common ingredient substitutions don't use 1:1 ratios. Honey is sweeter than sugar so you use less (×0.75); butter is 80% fat so you use more than oil (×1.25); cornstarch is twice as effective as flour for thickening (×0.5). Use the lookup above for fast answers; the notes flag any extra-liquid adjustments.

Frequently asked

Why isn't honey-for-sugar a 1:1 swap?+
Honey is sweeter than sugar by about 25%, AND honey contains ~17% water. So you use less of it AND reduce other liquid in the recipe. The two effects roughly compensate so 0.75× honey + ¼ cup less liquid usually works.
Can I always swap baking powder for baking soda?+
Only if the recipe has an acid (buttermilk, yogurt, lemon, vinegar). Without acid, baking soda doesn't activate.
How does brown vs white sugar change a recipe?+
Same volume, slightly more moisture and a molasses note. Cookies turn out chewier with brown sugar.
Will whole-wheat flour change my baking?+
Yes — it absorbs more water and tastes nuttier. Add 1-2 tsp extra liquid per cup of whole-wheat flour swapped in.
How much cornstarch replaces 1 tbsp of flour as a thickener?+
½ tbsp of cornstarch. Slurry in cold liquid before adding to hot pan or it lumps.
